[llvm-commits] [PATCH] AddressSanitizer: runtime support for use-after-scope bugs.

[Alexey Samsonov]

Hi kcc,

This patch adds new type of bugs detected by ASan: use-after-scope.
See D140 in phabricator that would use functionality added in this patch.
Currently these two patches are only able to find "use-after-scope"
bugs that happen due to function inlining. We would be able to find
actual use-after-scope errors after teaching Clang to optionally
emit llvm.lifetime intrinsics for local variables.
